Sites & eCom so easy, Grandma can do it.
Muse's marketing headline "Sites & eCom so easy, Grandma can do it." stands out and certainly stops the scroll.
Using "Grandma" as a proxy for technological inexperience attempts to highlight just how easy Muse it to use. It's important to note that choosing an H1 like this may potentially alienate a subset of people. Muse weighed the pros and cons and decided that the pros won out (and I would agree).
This promise of simplicity for website and ecommerce creation is compelling. There are countless tools in the space and most have their fair share of annoyances and quirks.
Overall, Muse's H1 effectively communicates their core value proposition, making complicated website and ecommerce creation accessible to users of all technical skill levels.
